HENRI SANDOZ, OF TAVANNES, SWITZERLAND.

REGU LATOR FOR WATCHES.

SPECIFICATION forming part of Letters Patent No. 674,712, dated May 21, 1901.

Application filed January 4, 1Q01. Serial No. 42,050. (No model.)

To all whom it may concern:

Be it known that I, HENRI SANDOZ,,a citizen of the Republic of Switzerland, and a resident of Tavannes, canton of Bern, Switzerland, have invented certain new and useful Improvements in Regulators for Watches, of which the following is a true specification.

My invention is designed to enable the workman to get the approximate adjustment of the balance -spring quickly and readily when testing the watch and to enable him to effect the finer adjustments after the parts of my improvement have been put in place.

In the drawings, Figure-1 is a plan view of my invention, and Figs. 2 and 3 are detail views of modifications.

Referring to Fig. 1, the regulator-ring O has a tailpiece 0, provided with pins g g to engage the balance-spring. A series of teeth are provided on the ring, which are engaged by teeth of a star-wheel or pinion b, which is pivoted to the bridgeplate by. a screw a.

This pinion is carried by an arm E, which at its front end carries a toothed segment S by means of arms 6 e. Meshing with the'teeth of this segment is the pinion S, and connected with this pinion is the star-wheel F. The star-wheel is arranged to turn in a recess of the bridge, and either of its points may be brought around to the mark f. When the workman is about finishing the Watch and before the pinion b and arm E are placed in position, the regulator-ring C can be freely turned by him to get the approximate adj ustment of the balance-spring, and then by placing in position the pinion b and theparts connected therewith the fine adj ustments are Y secured. It will be noticed that both the pinmay be turned by a screw-driver or other suitable instrument in the hands of the workman.

In Fig. 2 I show a part cylindrical body G, having a notch r in one side, and by turning this by means of a screw-driver or by any other suitable means the segment S may be moved either way. This segment is connected with the arm E by the resilient arms 6 6", similar in all respects to the arms e 6', before described.

In Fig. 3 instead of a notched cylinder I may operate the toothed lever E by means of a finger R, pivoted at o. This finger may be cut out to provide a spring action of the finger against the segment S., thus dispensing with the spring-arms e e e 6" described. This spring action between the segment and the part which moves it causes the parts to maintain proper engagement.

I claim 1. In combination, the regulator-ring having the tailpiece to engage the balance-spring, and having teeth, the small pinion engaging said teeth, an arm connected with the small pinion, a segment connected to the said arm and a rotary device for moving the said segment, substantially as described. I

2. In combination, the regulator-ring having the tailpiece to engage the balance-spring, and having teeth, the small pinion engaging said teeth, an arm connected with the small pinion, a segment connected to the said arm, a rotary device for moving the said segment, and means for securing a yielding pressure between the said rotary device and the segment, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

I HENRI SANDOZ.
